Django 1.8 + DRF 3.4 + Django Filters 1.0.1 Won't Work on ViewSets Methods
I'm trying to use django-filters with django-rest-framework to implement get/url/params based filters, but it won't work with viewsets and shows no error. If I use a generics.ListAPIView for example, the filter works flawlessly! My project code: Models.py class OrderFeedBack(BaseModel): """ Receive the customer rating, vendor and staff feedback about a order. Once the vendor or the customer has written his feedbacks, they can't change it. Developer: gcavalcante8808 """ rating = models.IntegerField() customer_feedback = models.CharField(max_length=255, null=True, blank=True) vendor_feedback = models.TextField(null=True, blank=True) staff_feedback = models.TextField(null=True, blank=True) order = models.ForeignKey("Order") locked = models.BooleanField(default=False) Filters.py class OrderFeedBackViewSet(viewsets.ViewSet): authentication_classes = (TokenAuthentication, SessionAuthentication) permission_classes = (IsAuthenticated,) filter_class = (OrderFeedBackFilter,) filter_backend = (filters.DjangoFilterBackend,) filter_fields = ('id', 'locked') search_fields = ('id', 'order',) def list(self, request): """ List all Order Feedbacks. --- serializer: app.api_v1.serializers.OrderFeedBackSerializer omit_serializer: false responseMessages: - code: 401 message: AuthenticationNeeded - code: 200 message: List of Feedbacks.

Converting Django model data to variables usable in Javascript
I am new to programming and to SO. I have a question about developing with Django / Python. I am trying to use django variables into a javascript script. My model is like this: class Business(models.Model): business_name = models.CharField(max_length=200) lat = models.FloatField(default=0) lng = models.FloatField(default=0) I am creating a Django app that sends the businesses data to a template def index(request): business_list = Business.objects.all() context = {'business_list': business_list} return render(request, 'kitemap/index.html', context) I would like to transform the list of django objects into a list of objects usable in javascript but i can't manage to do so...i tried the code below but did not work. Could you please help? Thanks for (var i = 0; i < {{ business_list|length }}; i++) { var school = []; business[0] = {{ business_list.i.lat }}; business[1] = {{ business_list.i.lng }}; business[2] = {{ business_list.i.business_name }}M businesses[i] = business; } -
Setting session variables vs setting variable in browser cookie (Django app)
I need to clear a concept. I'm tracking unauthenticated users in my Django web app via setting a temp_id that's set in the request.session dictionary as soon as a new user hits the web app's landing page. The code is is simply: temp_id = request.session.get('temp_id',None) if not temp_id: request.session['temp_id'] = get_temp_id() So far so good. Apart from saving a temp_id in request.session, another technique I could have used is setting a browser cookie explicitly for unauthenticated users like so: if not request.session.exists(request.session.session_key): request.session.create() The concept I'd like to clarify is are these approaches equivalent? I feel they are. My reasoning is that a browser cookie is merely a reference to a Session stored in the DB. And if cookies were turned off, matching a Session for that user would be impossible. Thus, regardless of whichever approach I take, I'll be relying on the browser's ability to store a cookie. Or in other words, both methods of allotting a temp_id to an unauthenticated user are, under the hood, quite similar. The only difference is that browser cookies are less secure than session variables. Can someone point out whether this line of thinking is correct? Or is my approach wrong? I'm essentially … -
Django time convert format
I am trying to convert time into specific format using following code: datetime.datetime.strptime(timezone.now() + timedelta(days=14), '%Y-%m-%dT%H:%M:%S.%f%z') I am getting error that the first parameter has to be string. I also tried using this code datetime.datetime.strptime(str(timezone.now() + timedelta(days=14)), '%Y-%m-%dT%H:%M:%S.%f%z') But then I am getting following error: time data '2017-06-04 14:26:18.941458+00:00' does not match format '%Y-%m-%dT%H:%M:%S.%f%z' Can someone suggest how can I convert to the specific format.

Saving file created inside the view to the backend (Django)
I have the following model : def upload_to(instance, filename): return os.path.join('/%s/' % instance.user.username, filename) class UserAudioAnswer(models.Model): user = models.ForeignKey(settings.AUTH_USER_MODEL) question = models.ForeignKey(Question) audio_file = models.FileField(upload_to=upload_to) translated_english_answer = models.TextField(null=True, blank=True) my_points = models.IntegerField(default=-1) def __unicode__(self): return self.question.text Inside my view I am recording an audio file from the user as follows: def start_recording(r,request): print("Reached start recording metho. About to start recording") with sr.Microphone() as source: print("Say something!") audio = r.record(source,duration=5) return audio My MEDIA_ROOT is defined as below: MEDIA_URL = '/media/' MEDIA_ROOT = os.path.join(os.path.dirname(BASE_DIR), "static_in_env", "media_root") So in this media_root folder I have to create a folder with the user name and then save the file inside it. I created the upload_to function to save my file there. I have done the following: 1) user_audio_answer = UserAudioAnswer() user_audio_answer.audio_file.save = (random_file_name,File(f)) user_audio_answer.audio_file = settings.MEDIA_ROOT+"/"+request.user.username+"/"+random_file_name+".flac" but it does not save anything. 2) user_audio_answer.audio_file = settings.MEDIA_ROOT+"/"+request.user.username+"/"+random_file_name+".flac" It saves the path of the file but the path starts from /Users/username/desktop and it goes on. What is the correct way to save the file to my backend, the way I am doing it?` -

JQUERY, select ID

We can add at once a lot of questions, as a an owner (author) we have to decide what is a 'type' of answers by selecting from dropdown list. var num_question_options = [0]; var num_questions = 1; $('#add-question-btn').click(function () { $('.questions').append( '<div class="questions-div" id="question-' + num_questions + '">' + '<label id="question-label" for="question-text">id:' + num_questions + '</label>' + '<input class="form-control" id="question-text" type="text" placeholder="Pytanie"/>' + '<div class="select-select-type">' + '<div class="dropdown">' + '<select title="type" class="select-type form-control" id="select-' + num_questions + '">' + '<option value="text">Krótka odpowiedz</option>' + '<option value="radio">Wielokrotny wybór</option>' + '<option value="checkbox">Pola wyboru</option>' + '<option value="menu">Menu</option>' + '<option value="scale">Skala liniowa</option>' + // tego na razie nie bedzie // '<option value="table">Siatka wielokrotnego wyboru</option>' + '<option value="date">Data</option>' + '<option value="hour">Godznia</option>' + '</select>' + '</div>' + '<ul id="answers" class="list-unstyled"></ul>' + '</div>' ); num_question_options[num_questions] = 0; num_questions++ }); Depending on selected answer type we should receive a place for typing possible answers (as author).

Cannot load static JS and CSS files in Django Project with GAE

Django CSRF Verification failed for admin panel
I started a fresh Django 1.11 project with one app, one model and one admin panel. Locally, everything works. When I deploy it to Amazon EC2 and try to log in to the admin panel, I get a 403 (CSRF verification failed. Request aborted.). I inspected with Chrome's network utility the request, and I noticed that in my Request Header I have: Cookie:csrftoken=hFhzOJPMOhkNWWWfRtlMOEum9jXV8XXWnOtw3OwZm2En9JUqYRVq632xyZfwSpzU while in my Form Data I have: csrfmiddlewaretoken:RHNpPfOHhg42FZnXmn9PZgNm3bN40C41XQZm4kvUP1oCSMl8tLJthFlxsR5FK4GZ Should these two be the same? In my understanding they do, but when I try the same in my local environment, I see they're also not the same, but there it is working fine and I get the same token back in the Response Header as was sent in the Request Header, so I assume they don't need to be exactly the same?

Why do Django have too many login redirects when using @login_required decorator?
I have searched for similar questions and answers for the question.I expect the home page to be displayed after authentication by a django-allauth view.But why do i have too many login redirects when using @login_required decorator?" Can you please explain the cause and the solution for the redirect loop? The code for the redirect loop is HTTP/1.1'' 302. I looked up from the Django documentation that @login_required decorator does the following: If the user isn’t logged in, redirect to /accounts/login/, passing the current absolute URL in the query string as next, for example:/accounts/login/?next=/polls/3/. If the user is logged in, execute the view normally. The view code can then assume that the user is logged in. I want authenticated users to proceed to home page, while redirecting not logged in users to accounts/login page. Part of my settings.py : LOGIN_URL='/accounts/login/' LOGIN_REDIRECT_URL='/' My views.py : from django.shortcuts import render from django.template import RequestContext from django.contrib.auth.decorators import login_required # Create your views here. @login_required def home(request): context={} template='home.html' return render(request, template,context) My urls.py : from django.conf import settings from django.conf.urls.static import static from django.conf.urls import url, include from django.contrib import admin from profiles import views as profiles_views urlpatterns=[ url(r'^admin/',admin.site.urls), url(r'$',profiles_views.home,name='home'), url(r'^accounts/',include('allauth.urls')), -
Django model filter with dynamic fields-vlues list
If there is a way to pass a list of values which vary in size depending on the values send by the user. This is a fundamental requirement in a user query. For an example, suppose a model as follows which have 3 fields. class MyModel(models.Model) Fiedl1 //say an int field Field2 //int field Field3 //char field In the user search form all fields are optional and there can be three combinations that user can query for particular objects. User do not set any field in the form (could be handle by default url) User only set values for two fields only. user set all values for the query. (similar to 2) My understanding is that pass only available fields in the POST request will do the trick. How can I do that? I look for correct and less coding solution for this. -
